The present disclosure relates to an implement including a handle (e.g., a telescoping handle), and more particularly to a control assembly coupled to the telescoping handle that controls operation of the implement.
In one aspect, an implement is configured to be supported on a surface. The implement includes a main body, a working member coupled to the main body, and a motor coupled to the main body. The motor is operable to move the working member. The implement also includes a handle configured to guide the implement during operation. The handle includes a first member coupled to the main body, a second member movably coupled to the first member between a retracted position and an extended position, and a locking mechanism coupled between the first member and the second member, the locking mechanism moveable between a locked position, in which the second member is fixed relative to the first member, and an unlocked position, in which the second member is movable relative to the first member. The implement further includes a control assembly configured to allow operation of the implement in response to the locking mechanism being moved into the locked position.
In another aspect, a handle is configured to be coupled to an implement to guide the implement during operation. The handle includes a first member configured to be coupled to a main body of the implement, a second member movably coupled to the first member between a retracted position and an extended position, and a locking mechanism coupled between the first member and the second member. The locking mechanism is moveable between a locked position, in which the second member is fixed relative to the first member, and an unlocked position, in which the second member is movable relative to the first member. The handle also includes a control assembly configured to allow operation of the implement in response to the locking mechanism being moved into the locked position.
In yet another aspect, a handle is configured to be coupled to an implement to guide the implement during operation. The handle includes a first member configured to be coupled to a main body of the implement, a second member movably coupled to the first member between a retracted position and an extended position, and a locking mechanism coupled between the first member and the second member. The locking mechanism is moveable between a locked position, in which the second member is fixed relative to the first member, and an unlocked position, in which the second member is movable relative to the first member. The handle also includes a control assembly having a control processor configured to detect when the locking mechanism is in the unlocked position, disable operation of the implement when the locking mechanism is in the unlocked position, detect when the locking mechanism is in the locked position, and allow operation of the implement when the locking mechanism is in the locked position.
Other aspects of the disclosure will become apparent by consideration of the detailed description and accompanying drawings.
Before any embodiments of the disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The disclosure is capable of supporting other embodiments and being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. Terms of degree, such as “substantially,” “about,” “approximately,” etc. are understood by those of ordinary skill to refer to reasonable ranges outside of the given value, for example, general tolerances associated with manufacturing, assembly, and use of the described embodiments.

With continued reference to
As shown in
In particular, when the telescoping handle 45 is in the retracted position (
Once the lever 90 is moved into the unlocked position (
With reference to
The illustrated control assembly 375 is coupled to the locking mechanism 80 such that the inner tubes 70 move relative to the control assembly 375 when the telescoping handle 45 moves between the extended position and the retracted position. In particular, the control assembly 375 includes a position sensor 380 having a first sensor 405 fixed relative to the outer tube 60. In the illustrated embodiment, the first sensor 405 is coupled to the sleeve 100, which is fixed to the outer tube 60. In other embodiments, the first sensor 405 can be spaced from the sleeve 100. The position sensor 380 also includes a second sensor 410 coupled to the pin 150, which moves axially relative to the sleeve 100 and the first sensor 405. Accordingly, the position sensor 380 is a hall effect sensor that detects a position of the second sensor 410 relative to the first sensor 405. The position sensor 380 is electrically coupled to the control processor 35 by wires routed externally relative to the outer and inner tubes 60, 70.
When the telescoping handle 45 is in the retracted position (
Once the locking mechanism 80 is moved into the unlocked position (
With reference to
In other embodiments, the position sensor 380 can be a contact switch or a proximity sensor between the cam member 95 and the sleeve 100/the outer tube 60. For example, the position sensor 380 can be coupled to an outboard surface 415 of the sleeve 100 (
In other embodiments, the position sensor 380 can be a contact switch or surface switch positioned between the lever 90 and the cam member 95 to detect relative movement (e.g., rotational relative movement) of the lever 90 and the cam member 95. For example, the position sensor 380 can be coupled to an inboard surface of the lever 90 (in one embodiment, the position sensor 380 can replace at least one of the protrusions 125) such that engagement of the position sensor 380 and the raised surface 130 of the cam member 95 is detected as the locked position of the locking mechanism 80 to allow operation of the lawnmower 10. Conversely, disengagement of the position sensor 380 and the raised surface 130 disables operation of the lawnmower 10. In some embodiments, the position sensor 380 can be coupled to an outboard surface of the cam member 95 (e.g., coupled to the raised surface 130 or the recessed surface 135). In further embodiments, the position sensor 380 can be between the cam member 95 and the housing 85 of the locking mechanism 80 to detect a position of the cam member 95 relative to the housing 85. In yet further embodiments, the locking mechanism 80 can include a clip latch with the position sensor 380 between two opposing contact surfaces of the clip latch.
Although the disclosure has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the scope and spirit of one or more independent aspects of the disclosure as described. Various features and advantages of the disclosure are set forth in the following claims.
